, SPLICING DEVICE FOR JOINING THE ENDS 0F BELTS.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed. January 28, 1919. Serial No. 273,647.

To all whom it may concern:

Be it known that I, O'r'ro CZARAN, subject of Austria-Hungary, and resident of Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Splicing Devices for Joining the Ends of Belts, of which the following is a specification.

This invention relates to splicing macliines for oining the ends of belts and the li (e.

The construction embodies means for forming the ends of the belt to the desired shape and means for holding the ends under the pressure whilethe cement is setting to make a permanent splice joint.

In the drawing forming. a part of this specification,

Figure 1 is a vertical longitudinal sectional view of the machine embodying my invention and disclosing the cutting por tion of the die;

Fig. 2 is a vertical cross-sectional view on line 22 of Fig.1;

Fig. 3 is an inverted plan view of the cut ting die and the under surface of the pressing means for holding the ends of the belt together while the cement is setting.

Fig. 4: is a view illustrating the ends of the belt as they appear after splicing and discloses the novel form ofthe splice joint.

Referring in detail to the drawing, A indicates the main frame in the base of which is formed the female portion '13 of the die. C indicates the presser portion in which is formed a housing C for the male portion D of the die. Thehousing is orovided with end guiding means E, and on which travel in slots F and F formed in the frame A. The portion D of the die is provided with a stem D which extends upward through the casting C in sliding relation therewith, terminates in a bifurcated portion D and a pin I extends through the sides of the bifurcated portion and the slot H formed in the operating lever G, one end of which is pivoted to the frame A as at H. A helical spring J is interposed between the top of the presser element C and-abuts the underside of the bifurcated portion D of the stem D and serves to hold the die portion D in its normal upper position in the element C.

Formed in the base portion B is also a groove B which registers with a groove B formed in the presser portion, so that when When the two ends of the belt to be spliced. are put into the machine with the ends abutting these would rest in alinement with the line 22 in Fig. 1. When the lever is forced downward the spring forces the presser portion G down upon the belt to hold the same in firm contact with the female portion of the die and a further movem'ent of the lever increases the pressure on theends of the belt through the instrumentality of the spring J, while the male portion D of the die cuts the ends of the belt to the proper shape, so that when they are placed together as shown in Fig. 4 they form a spear-head jointed. As illustrated, the slotted portion indicated by L in the end L is formed by one end of the die D and the projecting central portion M is formed in the end M by the opposite end of the portion D both of which act, of course, in cooperation with the correspond ing' female portions of the die.

After the ends of the die thus formed and put together with cement, as illustrated in Fig. 4, the ends are placed in the slot B and the upper part of the presser portion B is forced 'down upon the belt to squeeze the ends firmly together and thus insure a strong joint.

It is obvious that if the belting is of different shape the grooves B, B and C C can be made square instead of round, or of any other desired shape to correspond to the given cross-section of belting.

Having thus described my invention, I claim z- 1. A belt splicing device comprising a base portion having two female die portions formed therein and a groove conforming to the shape of the belt to be spliced, cutting dies located above said female portions and in alinement therewith, means whereby said cutting dies may be forced downward into engagement with the female portions thereof, and means for holding the two ends of a belt, and means co-acting with said cutting dies to hold the belt in position to be acted upon thereby.

2. A splicing device for round belting comprising a housing member and a base member having means for simultaneously shaping the two ends of the round belt so as to form an interlocking joint when said ends are fitted one into the other and means extending over the entire length of said shaped ends for applying pressure to said ends.

3. A belt splicing device comprising a base portion having two female die portions formed therein and a groove conforming to the shape of the belt to be spliced, cutting dies located above said female portions and in alinement therewith, means whereby said cutting dies may be forced downward into engagement with the female portions thereof, and means for guiding said cutting dies in alinement with said female die portions 4. A belt splicing device comprising a base portion having two female die portions formed therein and a groove conforming to the shape of the belt to be spliced, cutting dies located above said female portions and in alinement therewith, means whereby said cutting dies may be forced downward into engagement with the female portions thereof, and means for guiding said cutting dies in alinement with said female die portions,

means for holding the two ends of a belt and means co-acting with said cutting dies to hold the belt in position to be acted upon thereof.

5. A belt splicing device comprising a frame comprising the base portion and a presser portion, a housing in said presser portion, a stem, cutting dies held to said stem operating within said housing, and corresponding female die portions located in said base portion.

6. A belt splicing device comprising a frame comprising the base portion and a presser portion, a housing in said presser portion, a stem, cutting dies held to said stem operating within said housing, and corresponding female die portions located in said base portion, and means for operating said stem. v m

7. A belt splicing device comprising a frame comprising the base portion and a presser portion, a housing in said presser portion, a stem, cutting dies held to said stem operating within said housing, and corresponding female die portions located in said base portion, slots formed in said frame and guiding means projecting from said housing adapted to operate within said slots to guide the cutting dies in alinement with said female die portion.

8. A belt splicing device comprising a frame comprising the base portion and a presser portion, a housing in said presser portion, a stem, cutting dies held to said stem operating within said housing, and corresponding female die portions located in said base portion, and means for operating said stem, said means comprising a lever pivoted to said frame.

9. A belt splicing device comprising a frame comprising the base portion and a presser portion, a housing in said presser portion, a stem, cutting dies held to said stem operating within said housing, and corresponding female die portions located in said base portion, and means for operating said stem, said means comprising a lever pivoted to said frame, and resilient means located between said stem and said housing whereby the belt is first rigidly held in position and further movement of the lever causes the die to cut the ends of the belt.
